What is a TransientTransactionError in Mongoose (or MongoDB)?

mongoparseerror: value for `compressors` must be at least one of: `snappy`, `zlib`
mongonetworkerror: connection closed
mongoose db

I have server.js and db.js The db.js file interacts with my database using Mongoose and I use server.js to call functions from db.js :

var mongoose = require('mongoose');
mongoose.connect('', { useNewUrlParser: true })
var Schema = mongoose.Schema;

module.exports = function () {
    var db = mongoose.connection;
    db.on('error', console.error.bind(console, 'connection error:'));
    return db.once('open', function() {
        console.log("Connected to DB")
        var postschema = new Schema({
            title: String,
            intro: String,
            body: String,
            author: String,
            timestamp: { type: Date, default: Date.now }

        var post = mongoose.model('post', postschema);

        return {
            newPost(title, intro, body, author) {
                var newpost = new post({
                    title: title,
                    intro: intro,
                    body: body,
                    author: author
            getPostsAll() {
                post.find({}, function (err, res) {
                    return (`Error:${err} Posts:${res}`)

And my server.js calls three functions from db.js :

var DB = require('./db.js')
var db = DB()

I don't understand why I get this error :

connection error: { MongoNetworkError: connection 4 to black-test-shard-00-01-ewyaf.mongodb.net:27017 closed

  name: 'MongoNetworkError',
  errorLabels: [ 'TransientTransactionError' ],
  [Symbol(mongoErrorContextSymbol)]: {} }

What am I doing wrong? I found an article but can't make anything of it.

Transactions are new in MongoDB 4.0 and Mongoose 5.2.0. Transactions let you execute multiple operations in isolation and potentially undo all the operations if one of them fails.

javascript, Transactions are new in MongoDB 4.0 and Mongoose 5.2.0. the transaction if your operation throws; Retrying in the event of a transient transaction error. In MongoDB, an operation on a single document is atomic. Because you can use embedded documents and arrays to capture relationships between data in a single document structure instead of normalizing across multiple documents and collections, this single-document atomicity obviates the need for multi-document transactions for many practical use cases.

I encountered this error when running the populatedb.js script in the MDN tutorial for Express/NodeJS.

The script was looking for a db connection starting with mongodb://, however my connection string from mongo started with mongodb+srv://.

I edited the script to check for this syntax instead, which resolved the error.

I hope this helps someone.

  • @SagnikPradhan I would like to add one weird thing here. I don't if I am wrong here though. I added my IP address which I got from command prompt(Ipconfig command) and it didn't work . But when I asked the cluster to fetch my IP Address, it fetched a different one and that worked. If somebody could explain why, I feel that It would add something to the above question.
  • @vibhorvaish It might have been your local IP Address.
  • The only thing I would add is that the a transienttransactionerror is an attempt on a transaction that isn't on the snapshot (previous data) and prior to taking the write lock. Most likely due to a network connection error or write conflict. Think of a write conflict as something that won't let you write or to take the write lock because of circumstances... i.e. and prior to doing any sort of commit.
  • This literally solved the above error. Thanks so much!
  • Wat? How did your IP switch from IPv4 to IPv6? :/ How did you "disable IPv6"?
  • @Bloke - I get IPv6 IP by connecting via phone mobile hotspot. I disable IPv6 using sysctl (see google for details).
  • Thanks for the answer! Could you please add a bit of detail on why the issue is happening, and why your answer fixes it?
  • As well as introducing security issues. Please do not do this.
